Note:
The barometric pressure as measured by the CDI System 550 is not a user-
adjustable parameter. You can compare this value with a measured barometric
pressure in the room if you suspect there is a problem.
Note: The number of calibrations remaining, as displayed under the gas level indica-
tors, reflects the approximate number of individual sensor calibrations left. If you are
calibrating sensors for both arterial and venous monitoring, the count will decrease
by two for each calibration procedure. A set of full gas bottles should provide enough
gas for approximately 80 individual sensor calibrations.
At any time during calibration, you can press the stop key (in the upper-right corner of
the monitor’s front panel) to halt the calibration process. You can then resume calibra-
tion by pressing the √ (OK) key.
If you run out of time and you need to abort the calibration, press the stop key. You
can then press the cancel (X) key to exit and return to Standby.
If you switch to operate mode and begin measurement without having completed the
two-point calibration, the CDI System 550 automatically uses the calibration values
specified for the Default Calibration option on the general setup screen (as follows):
„ If “Last calibration values” is selected for the Default Calibration option on the
general setup screen, the monitor will use the values from the previous complete
two-point calibration.
„
If “Factory default values” is specified, average calibration values preset at the
factory are used.
„
When using either source of default calibration values, an in-line calibration using
reference values (from your laboratory) can be used to improve the applicability of
these default values.
